Abstract
This paper presents a novel quantum signature scheme by using quantum quasi-cyclic low density parity check (QC-LDPC) codes and quantum hash function. We construct quantum public keys by using quantum QC-LDPC Codes. Decoding general linear codes is NP-complete problem. The security of our scheme relies on the fact that NP-complete problem can not be solved on quantum Turing machines. Based on this public-key, this paper also gives a numerical simulation and proves the scheme security. 1548-7741/
